Summary is the problem itself. If I add the Computer using MMC - it will never displayed in Domain Computers Group.
If I force to add attribute (similar to Domain Users) to that group - memberUID:comp$ for exapmle, or add a computer via another LDAP management tool (LAM for example), it will be displayed. But MMC don't uses this anyway.
And I even can't delete computer from right tab. Only by hands, as it was added.
May be this is because I have misconfigured SAMBA/LDAP but I check everything twice before become sure of this problem.
Yes I have errors like
pdb_get_group_sid: Failed to find Unix account for comp$
in my messages. But I can't figure out how to fix this.
And also I have this:
pdbedit -Lw sasha$
...
Unix username: comp$
NT username: comp$
Account Flags: [W ]
User SID: S-1-5-21-3882935298-3125378829-2517500288-21004
pdb_get_group_sid: Failed to find Unix account for comp$
Primary Group SID: (NULL SID)
Full Name: laptop
Home Directory: \\company-sever1\comp_
...
May be my problem near this?
